Google's smart contact lenses. Google/AP by [Alexandra Sifferlin](https://time.com/author/alexandra-sifferlin/) ## Alexandra Sifferlin Mar 25, 2015 10:11 PM UTC Google has been granted a patent for a contact lens with an embedded chip, The patent, which was discovered by [WebProNews](http://www.webpronews.com/google-was-just-granted-a-patent-for-manufacturing-contact-lenses-2015-03), features a sensor in the lens. Google has previously said that it is partnering with the pharmaceutical company Novartis to create a smart contact lens that could monitor blood sugar for people with diabetes. As TIME has [previously reported](http://techland.time.com/2014/01/16/google-contact-lens-will-measure-glucose-in-tears/), Google has been testing various prototypes of smart contact lens and is currently in talks with the U.S. Food and Drug Administration (FDA) about a lens that measures glucose levels in users’ tears. The company says the chip and sensor are embedded between two layers of contact lens material and a tiny pinhole lets tear fluid from the eye reach the glucose sensor, and the sensor can measure levels every second. Diabetics must currently prick their fingers throughout the day to measure blood sugar levels, but Google believes the contact lenses would be less invasive and allow people with diabetes to check glucose more often and more easily. When asked if the patent is indeed for the smart contact lens for diabetes patients, Google told TIME the company does not comment on patent filings. “We hold patents on a variety of ideas—some of those ideas later mature into real products or services, some don’t. Prospective product announcements should not necessarily be inferred from our patents,” a Google spokesperson said in an email. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3758763/google-smart-contact-lens/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3758763/google-smart-contact-lens/"},"headline":"Google Granted Patent for Smart Contact Lens","datePublished":"2015-03-25T22:11:41.000Z","dateModified":"2026-04-13T08:04:44.330Z","description":"May allow people with diabetes to easily measure glucose levels","url":"https://time.com/3758763/google-smart-contact-lens/","keywords":["Research","Tech","diabetes"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt05ee2cd7c4a2ff0e/69869be2cd804dd48fccbf11/google-contact-lens.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alexandra Sifferlin","jobTitle":null,"url":"https://time.com/author/alexandra-sifferlin/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt05ee2cd7c4a2ff0e/69869be2cd804dd48fccbf11/google-contact-lens.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Google This undated photo released by Google shows a contact lens Google is testing to explore tear glucose.
